.- A1iplication flled Nov ber s, 192s.v s riai noanaese- The generalobject of the invention is to,

6 provide a rotary ;amu"sement" device including a plurality ofsuspended swings whlch, not only swing outward from their points ofsuspension, but also travel outwardly and upwardly together withtheirpoints of suspension under the influence of centrifugal force, thusgiving the occupa'nts'of theswing a novel and exciting thrill.

A'more particular object is to provide an attachment which may beattached to the 'endsof the radial arms of an amusement device of therotary swing type, by means of which attachment additional swings may besuspended between the conventional swings of the device, so that suchadditional swings may, not only swing outwardly from their points ofsuspension, but also may swing outwardly and upwardly together withtheir points of suspension under the influence of centrifugal force.

V Other objects and advantages will appear hereinafter as thedescription progresses.

The invention is illustrated in the annexed drawing which forms a partof this specification and in which, i

Fig. 1 is a perspective of a rotary swing of the captive aeroplane typeembodying my invention. 7 r Fig. 2is a side elevation of my attachmentshown attached to the outer end of a radial arm of a rotaryswing. V

Fig. 3is a transverse vertical section taken on line 33 of Fig. 2. 7

Corresponding reference characters designate the same parts in all thefigures.

In Fig. 1 I have illustrated a rotary swing of the conventional type,comprising a tower structure 1, a vertical shaft 2, extending upwardlythrough the top of said tower and journaled in a bearing 3'in the upperend 15 of the tower, a spider 4 comprising a hub 5 and a plurality ofarms 6 extending radially from said hub which hub is secured on theshaft 2 and rests upon the bearing 3, anda plurality of swings 7,. intheform-of aeroplanes, suspended from the ends of the arms 6'by means-ofcables8, each of said swings being suspended by a pair of said cablesbetween a pair of adjacent arms.

My invention includes a track bar 10,

formed with a vertical securing flange 11 at 16 as pivots.

13. at its innerand outer ends respectively,

a; roller 14" mounted: to travel onsaid track, ashackle 15 verticallysuspended at its upper end from -aj shaft'l6-on;;wh;ich said roller isournaled, an, eye; 17: swivelly connected :at

18, to the lower end of said shackle below saidtrack bar,a pair ofcables 19 and 20 suspended at their upper ends from the eye 17 andaswing21 in the form of an aeroplane suspended from the lower ends of saidcables.

The securing flange 11 is secured by bolts -22to the head 23 on theouter end of a spider arm 6, and the track bar 10 extends outwardly andupwardly at an anglefrom said securing flange. .The stops 12 and 13extend upwardly from the track 10. The track 10 is T-shape in crosssection, its verticalflange 24 extendingupwardly from its transverseflange 25 which serves to reinforce the track.

The roller 14 rests upon the upper edge of the vertical flange 2 1 ofthe track 10 and said roller is formed with flanges 26 and 27 at itssides ."respectively, which flanges depend below the upper edge of the,track flange 24 over the sides respectively of said flange to preventthe roller running oil the track. The shackle 15 extends downwardly pastopposite sides of the track 10 and under the track asshownin Fig. 3. Aswing 21' suspended from a rollerl i'on a tracklO is Iswings 7.

. When the swing is rotated all the swings 7 and 21 swing outwardlyunder centrifugal force from their points of suspension, the swings 21swinging from the roller shafts As the speed of rotation of the swingincreases the rollers 14 travel outwardly on the tracks 10 untilarrested by the stop 13. 'The swings 21, thus not only swing. outwardlyfrom their points of suspension,

but travel bodily outward together with their points of suspension underthe influence of a supercentrifugal force, giving the occupants of theswings a novel and exciting thrill.

While'my invention is shown attached to a conventional swing it is notrestricted to such use. The invention may be constructed in a device byitself and without the swings 7 its inner end and witharcuate stops 12and It is obvious that variation and modifications of the inventionmaybe made without departing from the spirit of the invention.

Having thus described my invention, I claim: a a a I 1. Ineombinationwith a rotary swing; ineludin a rotary arm with aheadonitsouter en a track bar formed with a flange on its inner end and withstops, one at. its

outer end and another nearits inner end, said flange being bolted tosaid head with the track bar extending outwardly from said arm, a rollermounted totravel on said track bar between said stops, a swing, andmeans for suspendlng sa1d swing from sald roller.

2. In combination with a rotary swing including a rotary arm, a trackbar formed with a stop at its outer end and a stop at its inner end,means for seeuringsaid track bar at its inner end to the outer end ofsaid ro- RICHARD GARVEY.
